Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST gives you all the advantages of Mavic's Road Tubeless system including less rolling resistance and a smoother ride quality. When paired with the new Yksion Pro UST tubeless tires, you get a perfect union between the wheel and tire, ensuring easy, hassle-free installation and removal thanks to Mavic's proven UST technology. And no tubes means no friction with the tire, so you roll faster using less energy. You can also lower your tire pressure for a smoother, more compliant ride, even on rough roads, with a reduced risk of punctures. Beyond the benefits of tubeless, all the other favorite features of this wheel stay the same. A wider rim shape (17mm internally) allows for an 18% increase in air volume for your tires. That extra volume gives you a more controlled and comfortable ride without compromising efficiency. The Zicral alloy spokes are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel. Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20%. Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400g. Total wheel weight is about 1420g.

The Zipp 202 Firecrest Carbon Clincher retains a classic 32mm rim depth, but with a sturdier 25.4mm rim width for all-around use. This legendary climber's companion weighs just 1,450g, and features Sapim CX Sprint spokes to optimize torsional and lateral stiffness. Laced to the maintenance-free Zipp 77/177 hubset, you can count on best-in-class durability no matter where you decide to ride. Confident stopping power comes from a combination of heat-resistant resin used in the 202's construction and Tangente Platinum Pro Evoke brake pads that provide all-conditions reliability. Zipp includes an integrated valve extender with valve-core wrench, rim tape, and quick release.

When Zipp gave their top engineers in The Nest advanced development lab the task of shedding more weight from their lightest carbon clincher wheelset, the 202 Firecrest, while also improving rolling friction, aerodynamics, and braking, it was a very tall order. When they asked them to do all of this without sacrificing durability, it looked like an impossibility. But the NSW advanced development team delivered on every request and built the ultimate climbing wheelset, a climbing wheelset strong enough to use on every ride.
Engineered to be the fastest accelerating carbon clincher Zipp has ever made, 202 NSW flies up the toughest climbs, and then shaves even more time off of the descents to follow. And because extracting greater speed on the mountain is only half the battle, they built the 202 NSW to deliver the lowest aerodynamic drag available for a rim of this depth for speed everywhere else.
In order for a climbing wheelset to be world beating it has to do more than simply deliver low weight; it has to deliver uncompromising performance on every level. This is why Zipp engineers in The Nest chose to enhance the world’s fastest climbing carbon clincher, the 202 Firecrest.
With a new lighter carbon fiber layup for the 32mm deep 202 NSW, they’ve dropped weight where it matters most, at the outer edge of the wheel, while maintaining the durability and lateral stiffness that Firecrest is famous for. Then they reduced aerodynamic drag with ABLC Sawtooth technology and used ImPress graphics to ensure that nothing stood between the air flowing over the rim and the dimples made to smooth that flow. Knowing that there is no benefit to a wheelset that climbs fast and descends slow, NSW engineers incorporated their Showstopper brake track for the most confidence inspiring rim braking performance available, whether the road is wet or dry.
To further improve the wheelset’s rolling efficiency, the 202 NSW rim is laced to their groundbreaking Cognition hubset. Built around their Axial Clutch freehub technology, the Cognition rear hub is engineered to maintain speed when coasting by disengaging the ratchet mechanism. This technology enables the Cognition rear hub to deliver far less rolling friction than wheels using conventional freehubs—a real advantage when fighting through rolling foothills or when spun out on long descents.
Engineered for speed when approaching, ascending, traversing, and descending the world’s toughest mountain roads, the Zipp 202 NSW is a wheelset that can only come from one place, The Nest, where the world’s fastest wheels are made.
